Velocity curve from Acceleration


Recommended Posts

Hi All,

I am trying to get a Velocity curve from an accelerometer in LabVIEW. The accelerameter is in G's, and I convert it to m/s2 and then take the integral of it to get velocity curve. The problem I am running into is that my entire curve is always sloped one way or another. is it something I am doing wrong with my LabVIEW functions?

I am attaching the VI i have written to derive it (Written in LabVIEW 8.5). You see a sharp aceleration at the beginnning, a sudden decleration with a rebound and finally a stop. The acceleration data all adds up, and so does the velocity data except it is shifted downward.

Any help anyone could supply would be a huge help. I am in a bit of a bind with this one. Why is the data not a staight line (except for when the object has velocity)?

Thanks,

Paul
